The poll showed that Trump has lost ground since 2016 among white voters, down 12 percentage points in Georgia and 7 in North Carolina. The president has in particular lost ground among white voters with college degrees.
Biden leads Trump among female voters with at least 50 percent support in both states and has an overwhelming edge among African American voters, with Biden surpassing 80 percent in both states.
By a small margin, voters in both states give Trump the edge in dealing with the economy.
